TECHNICAL FIELD

This invention relates to media entertainment systems and, inparticular, to architectures that support media content descriptionmetadata.

BACKGROUND

Many media entertainment systems provide electronic programming guides(EPGs) that allow users to interactively select programs that they areinterested in. Systems that employ EPG technology typically displayprograms organized according to the channel on which the program will bebroadcast and the time at which the broadcast will occur. Informationidentifying a particular program typically includes the program title,and possibly a short description of the program.

Over time, a large amount of descriptive data may be generated that isassociated with a particular piece of media content (e.g., a movie).This data may include, for example, reviews of the content by variouscritics, user recommendations, rating information, and genreclassifications. A user may desire to make decisions about whichprograms to view based on descriptive data associated with programsbeyond the short descriptions typically displayed in an EPG.

SUMMARY

An architecture that supports media content descriptions is described.The media content description architecture has a system to receivemetadata that describes media content from one or more metadataproviders. The system typically generates composite descriptions basedon received metadata. The system provides media content descriptions toone or more program data providers.

DETAILED DESCRIPTION

Introduction

The following describes a media content description system. The mediacontent description system stores metadata related to media content(e.g., a movie, a television show, or a song). The metadata that themedia content description system stores is related to the content of themedia, independent of when or where the media content is available. Forexample, the metadata stored in the media content description system mayinclude the name of a movie, a list of actors in the movie, the name ofthe director of the movie, and one or more critic reviews of the movie.The metadata stored in the media content description system does notinclude television channels or times when a particular movie will bebroadcast. The media content description system provides the storedmetadata to content distribution systems, which provide the metadata, aswell as the associated media content to users.

Content Description Metadata Collection

FIG. 1 illustrates two categories of program data 100 that can beassociated with media. Media (e.g., a movie) can be associated withcontent description metadata 102 and instance description metadata 104.Content description metadata 102 is data pertaining to the mediacontent, for example, the director, actors, story line, ratings, criticopinions, reviews, and recommendations pertaining to a movie. Instancedescription metadata 104 is data pertaining to when and where the mediacontent is available. For example, the time and television channel onwhich a particular movie will be broadcast. Because content descriptionmetadata 102 is associated with the content of media, and not aparticular broadcast of the media, content description metadata may bemaintained and updated throughout the life of a particular mediacontent.

FIG. 2 illustrates the collection of content description metadataassociated with media over time. Content description metadata is firstavailable when the media 202 is created. For example, the name of amovie and the actors in the movie is content description metadata thatis available when a movie is produced. The content description metadatacan be stored in a repository 204 over the life of the media. Forexample, when a movie is produced, the name of the director, the namesof the actors, a description of the story line, and the rating of themovie may be stored in the repository 204 as content descriptionmetadata. Over time, more content description metadata may becomeavailable, and can be added to the repository 204. For example, afterthe movie is released, critic opinions and recommendations may becomeavailable. Because this is information related to the media contentitself (and not just a particular broadcast or showing of the mediacontent), this information is added to the repository 204. At a stilllater point in time, additional reviews of the media content may becomeavailable. These reviews may also be added to the repository 204.

Content description metadata is generated by many different sources(e.g., movie production companies, movie critics, television productioncompanies, individual viewers, etc.). A media content description systemstores content description metadata from multiple sources, and makes thecontent description metadata available to users.

The following discussion is directed to media-based entertainmentsystems, such as interactive TV networks, cable and satellite networksthat utilize electronic program guides, and Web-enabled TV networks.Client devices in such systems range from fall-resource clients withsubstantial memory and processing resources, such as TV-enabled personalcomputers and personal video recorders (PVRS) equipped with hard-disks,to low-resource clients with limited memory and/or processing resources,such as traditional set-top boxes while aspects of the described systemsand procedures can be used in any of these systems and for any types ofclient devices, they are described in the context of the followingexemplary environment.

Exemplary Environment

FIG. 3 illustrates an exemplary environment 300 in which the methods,systems, and data structures described herein may be implemented.Exemplary environment 300 is a media entertainment system thatfacilitates distribution of media and metadata associated with the mediato multiple users. The environment 300 includes one or more contentdescription metadata providers 302, a media content description system304, one or more program data providers 306, one or more contentproviders 308, a content distribution system 310, and multiple clientdevices 312(1), 312(2), . . . , 312(N) coupled to the contentdistribution system 310 via a broadcast network 314.

Content description metadata provider 302 provides content descriptionmetadata associated with media to media content description system 304.Example content description metadata providers are movie productioncompanies, movie distribution companies, movie critics, and musicproduction companies. Any person, company, system, or entity that isable to generate or supply media content description metadata may beconsidered a content description metadata provider 302.

Media content description system 304 stores media content descriptionmetadata associated with a plurality of metadata categories and storesmetadata received from one or more metadata providers 302. In oneimplementation, the media content description system 304 generatescomposite metadata based on metadata received from a plurality ofmetadata providers 302.

Media content description system 304 provides the media contentdescription metadata to program data provider 306. In oneimplementation, the media content description system 304 provides toprogram data provider 306, all of the stored metadata that is associatedwith a piece of media content (e.g., a In another implementation, themedia content description system 304 provides only the stored metadatathat is associated with the media content that was received from aparticular metadata provider.

In an alternate implementation, each metadata provider is assigned oneor more trust levels or rankings, which may be associated withparticular metadata categories that indicate how trustworthy metadatareceived from that metadata provider is. In this implementation, themetadata that is provided to the program data provider may be based onthe trust levels associated with the metadata providers from which themetadata was received.

In yet another implementation, media content description system 304generates composite metadata based on metadata received from a pluralityof metadata providers, and provides the composite metadata to theprogram data provider.

Various implementations are contemplated, in which, the media contentdescription system 304 may provide any combination of contentdescription metadata to program data provider 306.

Program data provider 306 includes an electronic program guide (EPG)database 316 and an EPG server 318. The EPG database 316 storeselectronic files of program data, which is used to generate anelectronic program guide (or, “program guide”). The program data storedby the EPG database will be referred to as EPG data and may includecontent description metadata 102 and instance description metadata 104.For example, the EPG database 316 may store program to titles, ratings,characters, descriptions, actor names, station identifiers, channelidentifiers, schedule information, and so on.

The EPG server 318 processes the EPG data prior to distribution togenerate a published version of the EPG data which contains programminginformation for all channels for one or more days. The processing mayinvolve any number of techniques to reduce, modify, or enhance the EPGdata. Such processes might include selection of content, contentcompression, format modification, and the like. The EPG server 318controls distribution of the published version of the EPG data fromprogram data provider 306 to the content distribution system 310 using,for example, a file transfer protocol (FTP) over a TCP/IP network (e.g.,Internet, UNIX, etc.).

Content provider 308 includes a content server 320 and stored content322, such as movies, television programs, commercials, music, andsimilar media content. Content server 320 controls distribution of thestored content 322 from content provider 308 to the content distributionsystem 310. Additionally, content server 320 controls distribution oflive media content (e.g., content that was not previously stored, suchas live feeds) and/or media content stored at other locations to thecontent distribution system 310.

Content distribution system 310 contains a broadcast transmitter 324 andone or more content and program data processors 326. Broadcasttransmitter 324 broadcasts signals, such as cable television signals,across broadcast network 314. Broadcast network 314 can include a cabletelevision network, RF, microwave, satellite, and/or data network, suchas the Internet, and may also include wired or wireless media using anybroadcast format or broadcast protocol. Additionally, broadcast network314 can be any type of network, using any type of network topology andany network communication protocol, and can be represented or otherwiseimplemented as a combination of two or more networks.

Content and program data processor 326 processes the media content andEPG data received from content provider 308 and program data provider306 prior to transmitting the media content and EPG data acrossbroadcast network 314. A particular content processor may encode, orotherwise process, the received content into a format that is understoodby the multiple client devices 312(1), 312(2), . . . , 312(N) coupled tobroadcast network 314. Although FIG. 3 shows a single program dataprovider 306, a single content provider 308, and a single contentdistribution system 310, environment 300 can include any number ofprogram data providers and content providers coupled to any number ofcontent distribution systems.

Content distribution system 310 is representative of a head end servicethat provides EPG data, as well as media content, to multiplesubscribers. Each content distribution system 310 may receive a slightlydifferent version of the EPG data that takes into account differentprogramming preferences and lineups. The EPG server 318 createsdifferent versions of EPG data (e.g., different versions of a programguide) that include those channels of relevance to respective head endservices. Content distribution system 310 transmits the EPG data to themultiple client devices 312(1), 312(2), . . . , 312(N). In oneimplementation, for example, distribution system 310 utilizes a carouselfile system to repeatedly broadcast the EPG data over an out-of-bandchannel to the client devices 312.

Client devices 312 can be implemented in multiple ways. For example, aclient device 312(1) receives broadcast content from a satellite-basedtransmitter via a satellite dish 328. Client device 312(1) is alsoreferred to as a set-top box or a satellite receiving device. Clientdevice 312(1) is coupled to a television 330(1) for presenting thecontent received by the client device, such as audio data and videodata, as well as a graphical user interface. A particular client device312 can be coupled to any number of televisions 330 and/or similardevices that can be implemented to display or otherwise render content.Similarly, any number of client devices 312 can be coupled to atelevision 330.

Client device 312(2) is also coupled to receive broadcast content frombroadcast network 314 and communicate the received content to associatedtelevision 330(2). Client device 312(N) is an example of a combinationtelevision 332 and integrated set-top box 334. In this example, thevarious components and functionality of the set-top box are incorporatedinto the television, rather than using two separate devices. The set-topbox incorporated into the television may receive broadcast signals via asatellite dish (similar to satellite dish 328) and/or via broadcastnetwork 314. A personal computer may also be a client device 312 capableof receiving and rendering EPG data and/or media content. In alternateimplementations, client devices 312 may receive broadcast signals viathe Internet or any other broadcast medium.

Each client 312 runs an electronic program guide (EPG) application thatutilizes the EPG data. An EPG application enables a TV viewer tonavigate through an onscreen program guide and locate television showsof interest to the viewer. With an EPG application, the TV viewer canlook at schedules of current and future programming, set reminders forupcoming programs, and/or enter instructions to record one or moretelevision shows.

Exemplary Media Content Description System

FIG. 4 illustrates selected components of media content descriptionsystem 304 shown in FIG. 3. Media content description system 304includes one or more metadata provider interfaces 402 that facilitatecommunication between media content description system 304 and one ormore metadata providers 302. Media content description system 304 alsoincludes one or more program data provider interfaces 404 thatfacilitate communication between media content description system 304and one or more program data providers 306.

Media content description system 304 includes one or more processors 406and one or more memory components 408. Examples of possible memorycomponents include a random access memory (RAM), a disk drive, a massstorage component, and a non-volatile memory (e.g., ROM, Flash, EPROM,EEPROM, etc.). Alternative implementations of the media contentdescription system can include a range of processing and memorycapabilities, and may include more or fewer types of memory componentsthan those described. Processor(s) 406 process various instructions tocontrol the operation of the media content description system 304 and tocommunicate with other electronic and computing devices.

An operating system 410, a content description metadata repository 412,a media person data repository 414, and a metadata provider datarepository 416 may be stored in memory 408 and executed on processor406. Content description metadata repository 412 stores structuredcontent description metadata associated with media content. Media persondata repository 414 stores structured data identifying people who areassociated with media content (e.g., actors, directors, etc.). Metadataprovider data repository 416 stores structured data that describesrelationships between content description metadata providers 302. Inalternate implementations, data repositories 412, 414, and 416 may beimplemented as one or more data repositories.

Exemplary Content Description Metadata Repository

Content description metadata repository 412 stores metadata associatedwith the content of media. The data repository may be implemented as arelational database, an object-oriented database, a set of one or moredata files, one or more XML files based on an XML schema, or any otherdata structure method. For the purposes of this discussion, an exemplarycontent description metadata repository will be described as an XMLfile.

FIG. 5 illustrates the structure of media content description metadatastored in an exemplary content description metadata repository.

XML File Details

The XML File Details metadata entity is used to store data associatedwith the XML file in which the content description metadata is stored.An example XML File Details entity has the following elements:

Content Description File Version

Date Time Content Description Created

Content Description Creator Person

Content Description Creator Organization

Language Used for Content Description

Schema Version Used

The Content Description File Version element stores a number thatindicates the version of the file. As data is added to a media contentdescription over time, multiple versions of the file may be stored.

The Date Time Content Description Created element stores the date andtime that the file was created.

The Content Description Creator Person element stores the name of theperson that created the file.

The Content Description Creator Organization element stores the name ofan organization that created the file.

The Language Used for Content Description element stores a value thatindicates the language in which the content description data isprovided. In an exemplary system, the value that is stored in theLanguage Used For Content Description element is a combination of alanguage code and name according to ISO 639. Examples include“de_German”, “es_Spanish”, and “en_English”. An example list of languagefield values is given in Table 1, below.

The Schema Version Used element stores a number that indicates theversion of an XML Schema associated with the XML file.

MCID

Each piece of media content is assigned a unique media contentidentifier (MCID), such as MCID(1), MCID(2), . . . , and MCID(N). Basedon the structure of content description metadata repository 412, theMCID metadata entity stores one instance of one element, which is theMCID. For example a particular movie would be identified by a uniqueMCID.

The MCID may be implemented as any type of unique identifier. In oneimplementation, the MCID is a concatenation of hexadecimalrepresentations of specific metadata category values stored in thecontent description metadata repository. The metadata categories thatare used to generate the MCID are assigned levels of significance withinthe MCID. An exemplary MCID is based on data stored in the Title,Episode Name, Version Detail, and Part Detail metadata categories, whichare described with reference to FIG. 7. The MCID is a structured stringof the form MCID_TITLE_EPISODE_VERSION_PART, where TITLE, EPISODE,VERSION, and PART are hexadecimal values generated based on valuesstored in the Title, Episode Name, Version Detail, and Part Detailmetadata category entities, respectively.

An example MCID is:MCID_(—)0050-004-c34d-47ef_(—)00d4_(—)002f-83a5_(—)03. In this example,“0050-004-c34d-47ef” is the TITLE portion of the MCID, based on datastored in the value element of the Title metadata entity; “00d4” is theEPISODE portion of the MCID, based on data stored in the value elementof the Episode Name metadata entity; “002f-83a5” is the VERSION portionof the MCID, based on data stored in the version reason element of theVersion Detail metadata entity; and “03” is the PART portion of theMCID, based on data stored in the part element of the Part Detailmetadata entity. The TITLE portion of the MCID (the 0050-004-c34d-47efin the above example) is the most significant, followed by the EPISODEportion (the 00d4 part in the above example), the VERSION portion (the002f-83a5 in the above example), and finally, the PART portion (the 03in the above example), which is the least significant. Related media canbe determined by comparing portions of the respective MCIDs. Forexample, for a television series, all episodes of the series areassigned MCIDs that have the same value in the TITLE portion, butdifferent values in the EPISODE, VERSION, and PART portions.

Metadata Category 1, Metadata Category 2, . . . , Metadata Category (N)

Media content description metadata stored in content descriptionmetadata repository 412 is structured according to categories of datathat may be associated with media content. These categories arerepresented in FIG. 5 as Metadata Category 1, Metadata Category 2, . . ., Metadata Category (N).

Media content description system 304 may receive content descriptionmetadata, in the same metadata category, associated with the same mediacontent, from a plurality of metadata providers 302. These multiplevalues may represent different opinions as to the value of an attributeassociated with the media content. For example, two metadata providers302 may each have different titles associated with the same mediacontent. For instance, for the same media content, a movie, one metadataprovider may associated the title, “Indiana Jones and the Temple ofDoom” while another metadata provider may associate the title, “IndianaJones: the Temple of Doom” with the same media content. To supportmultiple data values associated with each metadata category (e.g.,multiple opinions as to the value of an attribute), the contentdescription metadata repository 412 supports multiple entities withineach metadata category. Each entity includes one or more associatedelements.

In one implementation, the media content description system 304determines the order of multiple entities within a metadata categorybased on category-specific rankings that are associated with contentdescription metadata providers 302.

In an alternate implementation, the media content description system 304generates a composite entity based on entities received from a pluralityof metadata providers 302. When the media content description system 304generates a composite entity, it is listed first among a plurality ofentities, indicating that it has the highest rank.

In one implementation, the composite is generated based on trust levelsassociated with the metadata providers 302 that provided the metadata.Other ways of indicating relative order of entities within a metadatacategory may be used, including storing a rank indicator as part of theentity.

Exemplary Content Description Metadata Categories

FIG. 6 illustrates related types of content description metadatacategories. Content description metadata 102 can include many types ofrelated data, including identifying data 602, associated people 604,genre data 606, content descriptions 608, popularity 610, censor ratings612, technical details 614, production details 616, enhancements 618,language data 620, and schema implementation details 622. Identifyingdata 602 includes any data that identifies media content, such as amovie title. Other types of metadata (e.g., 604-622) associated with themedia content are related to the identifying data 602, and describeattributes of the media content.

Identifying Data 602

FIG. 7 illustrates example identifying data categories. Identifying data602 includes metadata categories that identify the media content.Example identifying data categories include alternate contentidentifiers, title, episode name, album, version detail, and partdetail.

Alternate Content Identifiers

The Alternate Content Identifiers metadata category is used to mapcontent identifiers assigned by other metadata repositories to the MCIDassigned by the media content description system 304. An exampleAlternate Content Identifiers entity has the following elements:

Value

Entry Index

Entry Tag

MSI

Date Time.

The Value element stores a content identifier assigned to the mediacontent by another metadata repository. For example, a metadata provider302 may assign unique identifiers to media content within a proprietarydata repository.

The Entry Index and Entry Tag elements are elements in most metadatacategory entities and support multiple entity entries from one metadataprovider, or in the case of a composite description, the Entry Index andEntry Tag elements may be used to differentiate between multipleopinions as to the value of an attribute of the media content. Forexample, one metadata provider may assign multiple identifiers to thesame media content. The metadata provider specifies the order ofimportance of the multiple entries using the Entry Index field. Themetadata provider can provide information as to why each different entryexists in the Entry Tag elements of each Alternate Content Identifiersentity. Alternatively, in a composite description, alternate contentidentifiers received from multiple metadata providers may bedistinguished based on the Entry Index and Entry Tag elements.

The MSI element stores a metadata source identifier, which is a uniqueidentifier assigned by the media content description system 304 toidentify each metadata provider 302. The MSI, along with other datarelated to a metadata provider 302 is stored in metadata provider datarepository 416. The structure of metadata provider data repository 416is described with reference to FIGS. 20-22.

The Date Time element stores a date/time stamp indicating when themetadata associated with the Alternate Content Identifiers entity wasreceived from the metadata provider 302.

The above descriptions for the Entry Index, Entry Tag, MSI, and DateTime elements apply for each record described below that may contain anycombination of these fields.

Title

The Title metadata category is used to store one or more titlesassociated with the media content. An example entity within the Titlemetadata category has the following elements:

Value

Entry Index

Entry Tag

MSI

Date Time

Language

The Value element stores a title associated with the media content. Forexample, the value element may contain, “Friends,” to indicate thetelevision series by that name, or may contain, “Indiana Jones and theTemple of Doom,” to indicate the movie by that name.

The Entry Index and Entry Tag elements are described above and indicatethat a metadata provider may submit multiple opinions as to the titleassociated with the media content, or a composite description mayindicate various opinions as to the title, the opinions submitted bymultiple metadata providers. For example, titles may be submitted inmore than one language, or with different spellings for one or morewords in the title.

The MSI element is described above and identifies the metadata provider.

The Date Time element is described above and indicates the date and timeat which the data was received.

The Language element stores an identifier of the language associatedwith the title stored in the Value element. As described above, astandard set of language identifiers may be used. An example of such astandard set of language identifiers is shown in Table 1. Many of themetadata categories described include a Language element. Unless statedotherwise, this description also applies to the Language elementassociated with metadata categories described below.

Episode Name

The Episode-Name metadata category is used to store data identifying anepisode name associated with the media content. An example entity withinan Episode Name metadata category has the following elements:

Value

Entry Index

Entry Tag

MSI

Date Time

Language

The Value element stores a name or description of the episode. Forexample, for metadata describing an episode of the television series,“Friends,” the Value element may contain, “The one where Ross getsmarried,” or for metadata describing an episode of the televisionseries, “Frasier,” the value element stores the actual name of theepisode, for example, “Bully for Martin.”

The Entry Index and Entry Tag elements are described above and indicatethat a metadata provider may submit multiple opinions as to the episodename or description associated with the media content, or a compositedescription may indicate various opinions as to the episode name, theopinions submitted by multiple metadata providers.

The MSI element is described above and identifies the metadata provider.

The Date Time element is described above and indicates the date and timeat which the data was received.

The Language element is described above and identifies the language inwhich the episode name or description is given.

Album

The Album metadata category is used to store the title of a music album.This metadata category is used when storing metadata associated with amusic track, for example, a song. An example entity within the Albummetadata category has the following elements:

Value

Entry Index

Entry Tag

MSI

Date Time

Language

The Value element stores the title of the album associated with themedia content.

The Entry Index and Entry Tag elements are described above and indicatethat a metadata provider may submit multiple album titles associatedwith the media content, For example a recording artist may produce asong for a particular album, and then at a later time, include the samesong on a greatest-hits album. In this case, the same metadata providermay submit metadata about the song, and relate the song to both theoriginal album and the greatest-hits album by submitting both albumtitles. In a composite description, the Entry Index and Entry Tagelements may differentiate between various opinions as to the title, theopinions submitted by multiple metadata providers

The MSI element is described above and identifies the metadata provider.

The Date Time element is described above and indicates the date and timeat which the data was received.

The Language element is described above and identifies the languageassociated with the album title.

Version Detail

The Version Detail metadata category is used to indicate why a mediacontent version was created. For example, a colorized version of anoriginally black-and-white movie can be indicated using the VersionDetail metadata category. An example entity within the Version Detailmetadata category has the following elements:

Version Reason

Version Description

Entry Index

Entry Tag

MSI

Date Time

Language

The Version Reason element stores a value that indicates the nature ofthe media content version. An example selection list of values for theVersion Reason element is given in Table 2.

TABLE 2 Unknown Original Edited_For_Language Edited_For_NudityEdited_For_Adult_Content Edited_For_Violence Edited_For_Duration UpdatedAspect_Ratio_Change Resolution_Reduction Resolution_Increase ColorizedLanguage_Dub Subtitle_Change Other

The Version Description element stores additional information about themedia content version.

Exemplary Metadata Provider Data Repository

Metadata provider data repository 416 stores data related to contentdescription metadata providers 302. The data repository may beimplemented as a relational database, an object-oriented database, a setof one or more data files, one or more XML files based on an XML schema,or any other data structure method. For the purposes of this discussion,an exemplary metadata provider data repository will be described as anXML file.

FIG. 20 illustrates the structure of metadata provider data stored in anexemplary metadata provider data repository 416. For each metadataprovider 302, metadata provider data repository 416 stores an MSI,identifying data, and one or more metadata category trust levels.

MSI

Each media description metadata provider 302 is assigned a uniquemetadata source identifier (MSI), such as MSI (1), MSI (2), . . . , andMSI (N). Example media description metadata providers 302 may includecompanies that have a content identifier scheme, companies that provideattributes and genre categorizations associated with media content, andcompanies and individuals who provide critic reviews. The MPI entitystores one instance of one element, which is the MPI.

Identifying Data

As shown in FIG. 20, metadata provider data repository 416 storesidentifying data that is associated with each metadata provider 302.FIG. 21 illustrates examples of identifying data that may be stored inassociation with a metadata provider 302. Identifying data may includecompany name, company URL, Scheme Details URL, Email Contact 1, EmailContact 2, Email Contact 3, Address Line 1, Address Line 2,Address Town,Address State, and Address Zip Code.

Company name is the name of the metadata provider 302.

Company URL is a website address associate with the metadata provider.Scheme details URL is an address associated with a website that detailsa content identifier scheme used by the metadata provider.

Email contact 1, email contact 2, and email contact 3 are emailaddresses associated with the metadata provider.

Address line 1, address line 2, address town, address state, and addresszip code are the parts of the metadata provider mailing address.

Metadata Category Trust Level 1-Metadata Category Trust Level (N)

As shown in FIG. 20, metadata provider data repository 416 storesmetadata category trust levels that are associated with each metadataprovider 302. The trust level for a metadata category that is associatedwith a provider indicates the level to which metadata in that categoryreceived from that provider is to be trusted as accurate. For example, ametadata provider may be highly trusted to provide accurate criticreviews of media content, but have a very low trust level associatedwith metadata describing technical details associated with mediacontent. In an exemplary embodiment, the trust level is stored as aninteger value between 0 and 100, with 0 being the lowest trust level and100 being the highest trust level.

In an alternate embodiment, each metadata provider is assigned stacklevel ratings for metadata categories. For each metadata category, theproviders are assigned an ordered rank. For example, if there are fivemetadata providers, then for each metadata category, each metadataprovider is assigned a stack level rank between 1 and 5, where 1 is thehighest rank.

Alternate implementations are contemplated, and may include othermethods for ranking or ordering data received from metadata providers302.

FIG. 22 illustrates examples of metadata category trust levels that maybe stored in association with a metadata provider 302. Metadata categorytrust levels may include trust levels associated with title, episode,version, parts, artists, director, producer, editor, script writer,lyrics writer, music composer, location date, duration, format, genredegrees, genre program type, genre intent, genre target audience, genreattributes, review, censor parental ratings, extended censor ratings,origination, features, copyright, textual description, and links.

In this implementation, a metadata category trust level may apply to aplurality of metadata categories. In an alternate implementation, ametadata provider 302 may be assigned trust levels such that each trustlevel corresponds to a metadata category. Additionally, alternateimplementations are contemplated that relate provider trust levels withdifferent groupings of metadata categories.

Methods for Storing, Media Content Description Metadata

FIG. 23 illustrates a process for storing media content descriptionmetadata. The process is illustrated as a set of operations shown asdiscrete blocks. The process may be implemented in any suitablehardware, software, firmware, or combination thereof. The order in whichthe operations are described is not to be construed as a limitation. Fordiscussion purposes and where appropriate, the process will be describedwith reference to the architecture 300 of FIG. 3 and the system 304 ofFIG. 4.

At block 2302, a media content description system 304 receives metadatafrom a metadata provider 302. For purposes of this discussion, it isassumed that the metadata received pertains to a particular mediacontent, such as a movie. If the media content description systemreceives metadata describing a plurality of media content, then theprocess is repeated for the metadata associated with each media contentdescribed.

At block 2304, the media content description system 304 determineswhether the received metadata includes metadata that describes one ormore persons associated with the media content. Given a movie as themedia content, persons that may be described who are associated with themedia content may include actors, directors, producers, andscreenwriters. If the received metadata does not include metadatadescribing one or more persons associated with the media content (e.g.,the no branch from block 2304), the process continues at block 2312.

If the received metadata includes metadata describing one or morepersons associated with the media content (e.g., the yes branch fromblock 2304), then, at block 2306, the media content description system304 identifies data that was received that is descriptive of a personassociated with the media content.

At block 2308, the media content description system 304 stores the datadescribing the person in a media person data repository 414. The processexecuted by the media content description system to store the data inthe media person data repository is described below in more detail withreference to FIG. 24.

At block 2310, the media content description system 304 determineswhether additional persons associated with the media content aredescribed by the received metadata.

If additional persons are described by the received metadata (e.g., the“yes” branch from block 2310), then the process is repeated beginning atblock 2306.

After all of the received data describing persons associated with themedia content is stored in the media person data repository (e.g., the“no” branch from block 2310), or if none of the received metadatadescribes persons associated with the media content (e.g., the “no”branch from block 2304), the media content description system 304populates a content description metadata repository 412 with thereceived media content description metadata (block 2312). The processexecuted by the media content description system to store the data inthe content description metadata repository is described below in moredetail with reference to FIG. 25.

Populating Media Person Data Repository

FIG. 24 illustrates a process for storing metadata that describes aperson associated with media content. The process is illustrated as aset of operations shown as discrete blocks. The process may beimplemented in any suitable hardware, software, firmware, or combinationthereof. The order in which the operations are described is not to beconstrued as a limitation. For discussion purposes and whereappropriate, the process will be described with reference to thearchitecture 300 of FIG. 3 and the system 304 of FIG. 4.

At block 2402, a media content description system 304 determines aunique identifier associated with the person described by the receivedmetadata. For example, if the received metadata describes the directorof a movie, media content description system 304 searches media persondata repository 414 for data describing the same person described by thereceived metadata. The media person data repository 414 may alreadycontain a description of the director of the movie.

For example, a description of the movie may have already been receivedfrom another content description metadata provider 302 that included adescription of the director. Alternatively, the director of the moviemay have directed another movie that is described in the media contentdescription system 304, or the director of the movie may also be anactor in another movie or television show described by data stored inthe media content description system 304. If the person is alreadydescribed by data in the media person data repository, then the mediacontent description system determines the media person identifier (MPI)that is associated with the already stored data as the MPI associatedwith the person described by the received metadata. If the person is notalready identified in the media person data repository, then mediacontent description system generates a new MPI to identify the persondescribed by the received metadata.

At block 2404, the media content description system 304 identifies acategory associated with the received metadata that describes a person(e.g., a person category as described with reference to FIGS. 18 and19). Person categories may include a name, gender, marital status,ethnic origin, or any of the other person categories listed in FIG. 19.

At block 2406, the media content description system 304 stores the isreceived metadata that applies to the identified person category as aperson category entity in media person data repository 414.

At block 2408, the media content description system 304 determineswhether an entity in the identified person category was already storedin the media person data repository 414 and associated with the persondescribed by the received metadata.

If there was already an entity in the identified person category storedin association with the described person (e.g., the “yes” branch fromblock 2408), then the media content description system 304 generates acomposite entity based on all of the entities stored in the identifiedperson category associated with the person (block 2410). The process forgenerating a composite entity is described below in more detail withreference to FIG. 26.

At block 2412, the media content description system 304 determineswhether the received metadata that describes the person includes datathat is associated with another person category.

If there is data associated with additional person categories, theprocess repeats, beginning at block 2404 (e.g., the “yes” branch fromblock 2412).

Populating Content Description Metadata Repository

FIG. 25 illustrates a process for storing metadata that describes themedia content. The process is illustrated as a set of operations shownas discrete blocks. The process may be implemented in any suitablehardware, software, firmware, or combination thereof. The order in whichthe operations are described is not to be construed as a limitation. Fordiscussion purposes and where appropriate, the process will be describedwith reference to the architecture 300 of FIG. 3 and the system 304 ofFIG. 4.

At block 2502, a media content description system 304 determines aunique identifier associated with the media content described by thereceived metadata. For example, media content description system 304searches content description metadata repository 412 for data describingthe same media content described by the received metadata (e.g., themovie described by the received metadata may already be described bydata stored in the content description metadata repository 412). If themedia content is already described by data in the content descriptionmetadata repository 412, then media content description system 304determines the media content identifier (MCID) associated with thealready stored data as the MCID associated with the media contentdescribed by the received metadata. If the media content is not alreadyidentified in the content description metadata repository 412, thenmedia content description system 304 generates a new MCID to associatewith the media content described by the received metadata.

At block 2504, the media content description system 304 identifies ametadata category associated with the received metadata (e.g., ametadata category as described with reference to FIGS. 5-17). Metadatacategories may include categories that describe genre, descriptions,popularity, censor ratings, technical details, or any of the othermetadata categories listed in FIGS. 6-17.

At block 2506, the media content description system 304 stores thereceived metadata that applies to the identified data category as ametadata category entity in content description metadata repository 412.

At block 2508, the media content description system 304 determineswhether an entity in the identified metadata category was already storedin the content description metadata repository and associated with themedia content described by the received metadata.

If there was already an entity in the identified metadata categorystored in association with the described media content (e.g., the “yes”branch from block 2508), then the media content description system 304generates a composite entity based on all of the entities stored in theidentified metadata category associated with the media content (block2510). The process for generating a composite entity is described belowin more detail with reference to FIG. 26.

At block 2512, the media content description system 304 determineswhether the received metadata that describes the media content includesdata that is associated with another metadata category.

If there is data associated with additional metadata categories, theprocess repeats, beginning at block 2504 (e.g., the “yes” branch fromblock 2512).

Generating a Composite Entity

FIG. 26 illustrates a process for generating a composite metadataentity. This process applies to generating composite entities in thecontent description metadata repository 412 or the media person datarepository 414. The process is illustrated as a set of operations shownas discrete blocks. The process may be implemented in any suitablehardware, software, firmware, or combination thereof. The order in whichthe operations are described is not to be construed as a limitation. Fordiscussion purposes and where appropriate, the process will be describedwith reference to the architecture 300 of FIG. 3 and the system 304 ofFIG. 4.

At block 2602, a media content description system 304 determines anelement of an entity within the metadata category for which a compositeentity is being generated.

At block 2604, the media content description system 304 determines thedistinct values of the element that are stored within the existingcategory entities.

At block 2606, the media content description system 304 determineswhether there is more than one distinct value stored for the element.

If there is only one distinct value stored for the element (e.g., the“no” branch from block 2606), the media content description system 304sets the value for the element within the composite entity to the onedistinct value already stored for the element. The process thencontinues at block 2614.

However, if there is more than one distinct value stored for the element(e.g., the “yes” branch from block 2606), then for each distinct value,the media content description system 304 determines the sum of the trustlevels associated with the providers of that value (block 2610).

At block 2612, the media content description system 304 sets the valuefor the element within the composite entity to the distinct value thathas the highest associated trust level summation, as determined at block2610.

At block 2614, the media content description system 304 determineswhether there are additional elements associated with an entity of themetadata category.

If there are additional elements associated with an entity of themetadata category (e.g., the “yes” branch from block 2614), then themedia content description system 304 continues the process at block2602.
